"…hence I have at least 10 [QUOs]…"…now that's a recommendation :-)

Now are the 2 sine wave outputs bipolar, or unipolar? So if I'd use these f=
or vibrato,
would my received pitch stay centered (increasing modulation amount just ma=
kes the
vibrato more intense, but does not shift the perceived center pitch)?

Curious regards,
Jan-Hinnerk
